Hello!
Can anyone help? I don't know what's wrong with my seedlings. I've grown autoflowers before but these are photoperiod plants just over 2 weeks old. Is it a deficiency or do I have a bug or fungus problem? Please help! Thank you!

Hello! Thanks for your message! Here are some pics of the whole set up and the whole plant. The pics of singular leaves are from other plants in the grow (worried its spreading!).

I have 4 photoperiod plants from barneys farm (pineapple express, critical kush and sour cream gelato) in 5 gallon flexipots with bio grow mix soil. I have biobizz fish-mix, top-max and bio-bloom and microbes for nutrients and canna pk 13/14 but haven't started any of them yet except the fish mix which I'm giving only 1ml per litre to start with. The light is 240 led on 18/6 light schedule about 8 inches from top of plants on about half of full brightness spectrum. Day temp with light on is between 21 and 25 degrees celcuis. Night temp it drops to about 20 I think (could be lower) i do keep a heat mat on to try keep temps up at night. I never want to check cos when the light is off I don't want to open the tent and disturb them. It's got condensation on the tent at the top. Is that bad? I have a normal fan and extractor fan on but doesn't make much difference to condensation levels. Any help really appreciated! Really worried!!! Thank you!!!

The spots on the leaves look a bit like the plants need calcium.

The light looks like it's too close to the plants. What's the wattage rating of the light? What's the setting on the dimmer?

I'll move the lights up! Thank you! it's a led 240 on just over 50 percent power.

Put your Light at 20" back the light to 75% power until they recover, but leave the light at 20" your cooking them! You want 77-80 Fahrenheit at the canopy nominal temp- looks like you have a good start. The BiGrow is precharged at 1.7 EC, 12-14-24, you will need to begin feeding after 30 days old, start with half dosage...I wouldn't dose them with cal/mag yet but you should always have it on hand https://a.co/d/b4t6FOx Botanicare Plus works best in Hydro.(coco)
