Hi, guys!
This is my very first growth and of course something is not right. I’ll be gradeful if you help me find the issue and resolve the problem.
Plant “A” was “born” on the 17.04, plant “B” on the 15.04. Plant “B” is a fast bud and is 2 days older, but looks way smaller. I planted it 2 days ahead because the sprout was ready to be seeded. Plant “A” is auto and is bigger but not as big as it should be for its age. The bigger one also has some very small white (i think) dots on its leaves. The soil i used was Plant Magic Plus + perlite which i mixed seperately. The lights are Marshydro LED TS1000, 150w. The light cycle is 20/4. I dont grow in a tent as i have a small closet. I keep the humidity 50-70% and the temperature between 20-25. One of the mistakes that Ive made and realised it today was that the lights have been working on 100% instead of 50%. I keep them 45, 50 cm away.
I also totally forgot to buy a PH tester, so i ordered one but it turned out to be for the soil, now i have to order a new one for water. I assume the problem in the stunt growth might be the PH being 7.5, 8.0 and the stress from the strong light but how can i fix the whole soil now? If i add PH down liquid in the water and water them is it not going to change the PH only around the roots? Also i forgot to add that i read in another forum that its good that the whole pot is moisturised, not only around the plant, so i added a bit more water and on the surface of the bigger plant i saw some mold which already dissapeared. I havent watered them in 3 days as now im scared not to overwater them. Any tips on how to help them grow a little bit faster and healthier? Thank you in advance!
