HELP! - Week 5 seedlings - twisting new growth + discoloration

Hey RIU Family,

So I recently germinated 5 seeds. 3 Auto White Widows (i49 Swedbank), and 2 Reg Double Rainbow Rainbow Cookies x Purple Hulk ( InHouse Genetics). Currently they seem to be very small for the age they are and it seems that the newer growth is twisting on the White Widows. There also seems to be some yellowing and even dead spots on some them. As for the Double Rainbow Cookies they are more or less in decent shape (still seem very small to me) but the first node leaves have this purplish reddish hue along the edges and tips. I would love some expertise and outside opinions on this matter. Thanks!

I should also note that I only just started feeding them nutes and that it is taking a very long time for the coco to dry out.

======================================
Lighting: 1200W Viparspectra LED
Medium: 70/30 Coco/Perlite
Light Cycle: 18/6
Nutes: 1g MegaCrop Plant Food



Double Rainbow Cookies:

I was watering with CalMag but I stopped when I started feeding it nutes

don't stop feeding the calmag its for the coco. the higher the surface area or the more coco you have the more calmag you need to supply it.

its possible you will go into P lockout , since there isn't any calmag the coco will release excess Phosphorus into the medium

when you feed calmag all the way through + proper levels for the plant you will have success

it may take some tinkering to find the Ppm levels that supply not only the plant but the coco aswell , you will always have 2 mouths to feed in that regard


this will include flushes, always always include calmag in a flush, or a "reset" is a better word.

Okay I do know for a fact I over watered them it’s probably why their so small stunted growth. It’s taking almost 7 days for the medium to dry out so it’s tough start with CalMag and not over water right now.

I usually water with CalMag in between feeds. A normal cycle for this last grow that I’m finishing up has just been 2 feeds and a CalMag water. Seemed to work for me after having so many micro issues for my first grow.

I’ve read that before I believe you or someone else on here sent me there. I really try hard to calculate my ppms and keep everything in range. Not sure if I’m doing it right but it seemed to have helped with a lot of what I’ve been experiencing on my other grow.

do you have a ppm meter

ppm is easy measure the base , so just stick it in, let's say for example your tap water starts at 100 for simplicity sake. if your goal is feeding 700ppm of feed then your end number is really 800ppm because 100+700=800
