Wtf is going on?

Hello RIU I have a few Cinderella 99's, but one has a problem. I think it might be nute burn mixed with heat stress. I have it in ff happy frog with no added nutes except indonesian bat guano at 2/4 tsp per gallon of H20, and 1/4 tsp of dyna gro protekt silica. Every other watering. Here are some pics. Its in a 3 gallon fabric pot, indoor under about 460w cfls, a combo of 2700k and 6700k. I dont check ph often, dont have meter. Use tap water.
.
PLEASE let me know what you think, any info, comments, replies appreciated. THank you

what are your temps at

hot soil, being fed guano e/o....................back off on the bat shit. it is very available for an organic nute, and will scorch your leaves like that. give it a gentle flush, and just feed during flower.

the silica is heavy too. let's see some right-side-up whole plant pics.....................

Right at this moment its at a perfect 75 degrees with humidity at 45%, BUT during the day it gets pretty hot, anywhere from 85 to 90 degrees. Today it was at 90 when I got home. I also just seen another leaf, completely yellow, but this is from a gdp plant. Here is the pic. On this one im almost sure its a nute deficiency, since ive heard gdp are a lil demanding on nutes, but what do you think its asking for? Thank you for your input!

How long has the plant been growing? cfls are cool the first week only
then you really need the HID lighting and some real nutes besides the
bat shit......

The c99 girls have been veggin for about 4 weeks since I got them. Before that they were under t-5's at 24/7. I have other plants like my northern lights and harlequin that have been veggin for about two months now, and when I started to veg them I had less than half the watts I have now, but they seem to have grown to a pretty nice size, both at 24" tall. I transplanted them about two weeks ago, into 5 gal fabric pots, which make the fox farm happy frog soil they have fairly new. Iv'e heard fox farm soil is pretty heavy with nutes, and that is why I havent fed them anything but silica and guano. I have a total of 21- 23watt clfs, with 12 bulbs being in the 6700k and ten in 2700k. It seems like only the c99's are doing it. Here is pic of the Northern lights ive had under the cfls for for at least eight weeks. Thanks for the reply!

Ok thank you! Yea it has gotten pretty hot in there, and the fabric pots, just as they cool the roots when hit with a nice breeze, it makes sense that if the temps are hot, the roots will feel it because of the fabric pot. I will stop giving them the guano for a while and see what happens. But to flush is that just feeding pure H20 with no nutes at all? Or do you need to do a certain process? Sorry new at this. Thank you very much for the info!

In soil, you do not need the silica. Silica supplements are for hydro and also have a way of upsetting pH toward the alkaline. My experience with C99 is that she's a hardy plant with much toleration for high nute levels. I would suspend all nutes until the plant shows appetite once again, except perhaps cal-mag. Those leaves look like they're combining overmuch N with not enough Ca, Mg, K. But Happy Frog by itself has those nutrients, except may be light on Mg. Just water for now ... is my advice. cncn

Ok here are some pics. Dont remember if I mentioned before, but this is the only one that seems to be doing it out of the three I have indoor. I noticed right now when I took the pics that the leaves seem to be getting worse. I took pics of those as well. I wanted to get these close to 2 feet and get the stem nice and strong since it is kind of thin and doesnt look to strong to support heavy bud growth, and once I had it to 2 feet and strong stem force flowering But idk if I should just start to flower it before it gets more problems. Thank you!

Ok thank you very much I will look into getting a cal-mag nute. I have ff microbrew, kangaroots, and grow big, but i havent fed them that yet, because of my assumption that ff soil had enough nutes for at least a couple of months. I will just give water for a couple of times and hopefully it gets better!

This won't help you with this grow, but one thing that does well for FF soils is to admix a bit of powdered dolomite lime. it corrects lightness in Ca and Mg, and it counters FF (sphagnum-based)'s tendency to drop its pH with time.
An excellent Mg supplement, if you're good with dosing it, is Epsom salt. one gram per liter translates to 100ppm Mg and 130ppm S. cn

Ok thank you! I will look into getting epsom salt, they sell it where I work. But on the being "good" with dosing, well I don't know what being good means! I mean, I usually just give half strength of what they ask, and I make sure to give it when im suppose to. Also, what would the 1gram per liter translate into gallons? I know I can look up the conversion online, but just want to make sure I get it right! If I decide not to go with epsom salt, is there an organic nute with the right amount of cal-mag? Thank you for your time and all the useful info! Really appreciate it.

The key to being "good" in this instance is to go by weight, and not measure your dry nutes by volume. Three point eight grams go into a gallon, with four being tolerable.
Organic? Not very sure. Bone meal is Ca and P, while dolomite lime is Ca and Mg. Gypsum is rapid-release Ca. Organic, soluble Mg ... I don't know. cn

Ok I see! 3.8 grams per gallon I understand much better! lol. I looked into dolomite lime and it seems to be an all natural combo of minerals so I guess it qualifies as organic! One more question, I saw general organics has a cal-mag liquid nute, and I also saw dry, powder dolomite lime, which do you recommend for soil? TY!

For soil? The dry, powdered stuff. I don't remember the amount to admix, but it'll be easy to find online, I reckon.
But if a soluble cal-mag is desired, I much prefer the Botanicare product to the GO one. GO is 5:1 Ca to Mg, which is too chalky for me. The Botanicare CalMag is about 2.6 to one, and the counterion is nitrate, which is also a nutrient. cn

Awesome thanks I really appreciate your help bud! I will get the dolomite lime tomorrow, but I will start feeding in about a week, just to see what it does being fed nothing but water. Thanks again for all your help!

A pleasure, and best luck. I enjoy conversing with people who ask sound questions. cn

You really know ur stuff

lock out,flush ,flush ro water 1/4 nutes phd
