Someone please help.. discoloration

I haven't gave them full strength nutes yet. On day 7 I fed them some Big Bloom (0.01%-0.3%-0.7%) at 1/8 strength, and I actually seen them dancing to it. They exploded. I transplanted on day 9 (4 days ago) and watered with reg water. Two days ago, I watered them with 1/4 str Big Bloom but nothing really happened. They aren't due to get their first round of N-heavy Grow Big (6-4-4) until Monday, but I think I am going to dose them up with half str Big Bloom and Grow Big when I water them in a few hours, instead of plain water like I was going to.

N deficiency could very well be... My medium right now is 65% potting soil and 35% perlite. The soil analysis is (0.21-0.07-0.14). Not very strong, I would think after 2 weeks or so of water every 2 days would drain that pretty quick.

Thanks for all the help so far; please let me know what you think of my solution before I do something terrible and have to start over:mad:

The rusty spots seem to be getting worse =(.

GetThisOrDie: I have the tester you suggested ordered, but for now I was just testing my plain distilled water with the drops. The way I tested the nute solution was to mix it up, let the particles settle, then skimmed the top of the clear water for a test. Its the best I could do for now.

Come to think of it... I have 3 plants total. One of the plants was growing ALOT slower than the other 2 initially, but has now caught up to the other 2. Since catching them in growth, it now too has starting yellowing from the bottom. Same exact thing. N deficiency is what I am thinking.

or maybe my terrible ph for the first 2 weeks has nute locked them. Rust spots are some trace mineral lockout from bad ph is what I was reading somewhere. same with nitrogen

Yes the N deficiency was probably due to PH being high. MG potting soil should last a bit longer than 2 weeks from seedling. Rusty dead spots also due to PH lockout. Get your PH under control and have you check the pot runoff?

Its hard with drops since the water will be discolored. Depending on the runoff you might need to flush the soil with ph corrected water.

After the PH is under control then you can worry about mixing the nutes up right.

just gave them some 1/4str Grow Big

6.7 in // 6.0 out

i think the soil is in the upper 5s for ph; should i run some plain water with ph up through them to bring it up? how would i go about bringing the ph up or do i just need to start over lol

5's are way too low. Try using some dolimite mulched into your soil about 4 inches deep, or some fine granulated lime powder mixed with water and poured from top through bottom of soil. Lime and doloimite are ph nuetral and should bring you to around 6.5 ph, in the 5's and you are nothing but acidic. 6.3 to 6.8 is your goal. I have been using Dr. Earth's organic 5 and it has done well for a fertilizer. I believe it settles at about 6.5 for ph so it levels out the soil just fine. It sits at 7N which is great for veg and flower.

yea, i watered them heavily with 7.8 pH water a couple of times... they are looking pretty good. Seem to be greening up and even put on some height in the past couple of hours... ill keep this updated till they are 100% again.

Woke up this morning and they look 50 times better. Definitely greening back up and put on about half an inch or so of height last night. Thanks for all the help guys; I'll keep updates on my log. Check the signature!:stoned:
