DTW liberty haze, masterblend nutrients.

[mark360jones]

Lights are now 25 inches from the canopy and turned up to 75% . Growth is looking great and all the ladies are doing extremely well (considering the start they had). They have bounced back with a vengeance after the haircut and have now been switched to 12/12. I am still lst the plants to keep the canopy even.
1 1/2 weeks left of growth nutrients and then on to my flowering mix.

Excelent growth, don't seem to be stretching an awful lot which I like. Ive pruned some leaf which was covering some potential bud sites. Pistols have started to show so hopefully bud formation will come on quick. I'm still using my growth mix and will probably use it up to the start of week 3 of 12/12 then I can switch out some nitrogen for pk and really get the girls packing on some weight

They look better and bigger :)

I just can't believe they were nearly dead a few weeks back (my own fault). these ladies can't have take some shit in veg. Flowering may not be so forgiving so I will be more careful now on

So the girls are coming along, it's been a week since 12/12 and there showing signs already. All is going great 1 more week to go and the I will start the flowering nutrients as they still need the nitrogen for growing.
From when I change the nutrients I start to count the weeks of flower as the 1st 2 I count a veg/preflower.
From what I was told this pheno is really quick and was done withing 6 weeks (8 if you add the 1st 2)

I've done a few grow room checks today and everything seems to be pretty much bang on. The sp3000 light don't half give off some light it's sitting at 24 inch from the canopy and it's only on 75%, I think I will need to raise it once I blast them with 100% (around week 3/4)

Had to do a little defoliating on all 8, airflow has been improved also shaded sites have been uncovered. Couldn't believe how sticky some of the large fan leave were, literally could see the sap type residue (anyone ever had this before?) which I've never come across before.

The leaves look a little crinkled up as I was shoving them into my pockest while I was defoliating as i forgot the bag .

Great bud formation starting now, I've swapped to flower nutrient schedule now 1/2 a day early so it's a really reduced nitrogen mix as the stretch seems to have slowed. 1/4 strength separate cal mag added just to keep these topped up throught flower, 1/4 strength pk also added and full dose boost. Im going to give the ladies a small trim tomorrow just to keep bud site from being shaded and airflow good. Lights are still set at 75% this will be changed to 100% at the start of week 4, Temperature is a constant 26c humidity is usually between 45 and 50rh, I've always kept the pH as close to 6ph as possible right throughout seed/cutting to harvest. Ec has now reduced to 1.2.

 

[mark360jones]

Great progress being made. Formation of flower is building fast but there does seem to have been a little extra stretching (hopefully means long fat buds), slight leaf tip burn so im happy im near optimum nutrient strength. Once the resovior is empty today I will be starting the bulking flower nutrient recipe, I will be upping the pk from 1/4 dose to 1/2 dose also the recipe steps down to virtually no calcium nitrate (13g in 260L) so I will keep have to keep a close eye on the calcium and upper the cal mag from 1/4 to 1/2 dose if there's any signs of deficiency.

Unbelievable that my main nutrients im using ive had them for nearly 3 years (cost me £200) and there's still loads left.

how much are they drinking? With that low RH I’ll bet they are full open stomata all day. Kinda droopy.

This is the original thread

The pic you sent me via pm shows nute burn. The pics in this thread do not. What has changed? Did you switch to flower nutes or change ratio?

I just replied to a post you previously commented on lol. I dunno how to just get peoples names up.

This is the updated today's photos. Start of week six flower tomorrow

@Moe.Red

did you change nutes?

I upped pk. So week 3 flower I did 1/4 strength of recommended dose. Week 4 1/2 strength recommended dose and kept it at this until now end of week 5 start of week 6. I was away for a few days and came back to this nutrient burn. When I left they seemed to be handling it.

 

[Moe.Red]

Well you are clearly listening to the plants. You were right there is nute burn. So something has gone wrong with your timings media or amount of water or ph.

I don’t run a drain to res system but to me that system has a con that results in what you are seeing if you are not fastidious with the process. I can’t remember is this coco? Does ph drift up and how do you handle that?

Yes this is coco. The pH is extremely stable in the resovior it can mabey drift 0.1 if even at all over a whole week. I think I may have added too much pk that these can handle. Do you think a good flush of pH 6 water then re Introduce nutrients at mabey 1.1 ec instead of 1.3ec.

 

[Moe.Red]

Sounds exactly right. Flush that coco in case you have a salt build up.

 

[Moe.Red]

You probably won’t see any improvement but just checking in.

I can’t remember if this is your first grow but it is looking really good. Looks like a few more weeks? Got your harvest dry and cure all sorted? They are squatty so I’ll wager 1.6 pounds dry. You can push tgat up next grow if poundage is what you are going for.
