Noticed some tip burn back on Mar 3. Could be your NPK ratios are off and lock out is occurring. Consider a trip into sick bay for professional help. She is a gorgeous plant. Let’s get her to the finish line,
You are watering off a reservoir with a wick system correct? Maybe check the water pH and EC. Do you add any nutes to the res or is it plain water?
I've had that happen a couple grows and going to a bit more feed seemed to help although I am in coco and with soil eh, I am not expert. I belive the transition point they need a boost, maybe something with good P/K to get over the hump? What have you got or been using?
The infirmary will get the attention of the pro growers for sure, just be certain to fill out the cut and paste "form."
I went ahead and posted in the infirmary. It’s just a bummer that this issue keeps popping up. Previously thought that with my tap water being loaded with calcium that, along with the lime in the soil, it was just too much calcium causing lockout. I cut my mix 25% with pro-mix to try and even it out and have switched to RO/DI water. Here’s the info I posted…
Problem: started with a little leaf tip discoloring and progressed to this. I was out of town 1.5 weeks and came home to her in this condition. I run into this in early flower. Previous grows I thought that I had too high of Ca in my water along with the lime in the soil. I cut the soil with 25% pro-mix to try and lower the Ca amount and have switched to RO water but the same problem has arisen yet again.
-Medium/grow method: DIY octopot wannabe, 7 gallon fabric pot with net cup in reservoir. Soil is homemade with 1:1:1 compost, EWC, and coco coir, with epsom salt and lime mixed in. Soil has baked for several months before use. When potting the soil, I put several tablespoons of Dr. Earth Homegrown and Flower Girl in buried trenches.
-Feed and supplements used: soil mixed with Dr. Earth Homegrown and Flower Girl mixed in, along with some epsom salt and lime. A little dynomyco at seed planting. I topdressed with EWC and watered in with LABs a few weeks ago. Only have added some Southern Ag Garden Friendly Fungicide to the res a couple of times. Otherwise water only to this point.
-Water source: RO/DI water using an AquaLife RO Buddy on my tap water
-Strain and age: Sour diesel photo by Seedstockers. Day 75, F 32
-Climate: 3x3 tent, temp 76-82F, humidity 64-69%. 12/12 light cycle
-
Light used: Mars Hydro FCe3000, ~16” above net, at about 60% brightness. Photone app reading ~750 ppfd, slowly bringing it up.
-Additional info: First real attempt at a scrog. Any help is appreciated, as always
